Hackaday Printing Press Upgrade

There comes a time when your movable type becomes so over-used that you no longer get a legible print off of the printing press. For months now we’ve been at work on a new site design that maintains the essence of Hackaday while ejecting the 10-year-old dregs of the site. With each small success we’ve actually ruined ourselves on viewing the old design. It is with great relief that we unveil a site design built specifically for Hackaday’s needs.

The most notable change is in the content of our landing page. For ten years, loading Hackaday.com resulted in the most … Read more

An Interview with Tesla Battery Hacker [wk057]

We covered [wk057] and his Tesla Model S battery teardown back in September. Since then we had some time to catch up with him, and ask a few questions.

You’ve mentioned that you have a (non hacked) Tesla Model S. What do you think of the car?

It’s the best car I’ve ever driven or owned, period. Not to get too into it, but, I love it. I’ve put almost 20,000 miles on it already in under a year and I have no real complaints. Software feature requests… but no complaints. After almost a year, multiple 1700-miles-in-a-weekend trips, and an … Read more

Hackaday Prize Finalist: A Network of Satellite Ground Stations

There are astonishing things you can do with a network of sensors spread across the globe, all connected to the Internet. Thousands of people have already installed hardware to detect lightning and flightaware gives out subscriptions to their premium service to anyone who will listen in to airplane transponders and send data back to their servers. The folks behind SatNOGS, one of the five finalists for The Hackaday Prize are using this same crowdsourced data collection for something that is literally out of this world: listening to the ever-increasing number of amateur satellites orbiting the planet.

There are dozens of … Read more

Hackaday Prize Finalist: A Portable SDR

No other project to make it to The Hackaday Prize has people throwing money at their computer screen hoping something would happen than [Michael Colton]‘s PortableSDR. It’s a software defined radio designed for coverage up to 30MHz. Amateur radio operators across the world are interested in this project, going so far as to call this the first Baofeng UV-5R killer. That’s extremely high praise.

[Michael] was kind enough to sit down and answer a few questions about how his entry to The Hackaday Prize has gone. You can check that out below, along with the final round video of … Read more

Developed on Hackaday: Crowd- funding Campaign Start!

For a little less than a year open source enthusiasts from all over the globe got together to work on an open source offline password keeper. We narrated our progress here on Hackaday and always asked our readers’ opinion when critical decisions were to be made.

Today, the wait is finally over: the Mooltipass crowdfunding campaign finally arrived.

In some of our Developed on Hackaday series posts we noticed that it was tricky for us to convey the benefits of the device we were developing. The first 3 minutes of our video therefore explain good security practices and how … Read more

  • Surfing Around on a Self-Balancing Cloud

    Surfing Around on a Self-Balancing Cloud

    By Sarah Petkus | November 13, 2014

    Throughout time it’s just been plain cool to genie around from point A to B on some form of personal portable hardware. Understandably so, it was the goal of [Dane Kouttron] to modify and improve the common standard in such a way that anyone could hop on his board and ride without a period of flailing to keep balance. In his Flying Nimbus project, the rider floats aloft a single power-driven wheel that will even do the balancing bit for you.

    Inspired by some interesting aluminum scraps and an old 3 phase DC servo driver, [Dane] starting conjuring ideas of … Read more

  • An External Autofocus for DSLRs

    An External Autofocus for DSLRs

    By Eric Evenchick | November 12, 2014

    Most modern DSLR cameras support shooting full HD video, which makes them a great cheap option for video production. However, if you’ve ever used a DSLR for video, you’ve probably ran into some limitations, including sluggish autofocus.

    Sensopoda tackles this issue by adding an external autofocus to your DSLR. With the camera in manual focus mode, the device drives the focus ring on the lens. This allows for custom focus control code to be implemented on an external controller.

    To focus on an object, the distance needs to be known. Sensopoda uses the HRLV-MaxSonar-EZ ultrasonic sensor for this task. An … Read more

    How To Get 50 More Zed From Your Rigol DS1054Z

    By Kristina Panos | November 12, 2014

    [Chris] has been spending a lot of time in the wife’s sewing room lately, and things got pretty serious late last night as he hacked his shiny new Rigol DS1054Z to unlock the 1104Z capabilities lurking within.

    The rumors are true, and ungoverning the software is as simple as looking up your serial number and knowing the right URL for generating a valid license. [Chris] ran into a dud site, but that’s the price of doing business in the shadowy parking garage basements of the interwebs. Once he knocked on the right door and uttered the secret word, however, he … Read more

  • $2 FM Transmitter for Raspberry Pi

    $2 FM Transmitter for Raspberry Pi

    By Elliot Williams | November 12, 2014

    We love re-purposed consumer gear. [Tobias] sent us the link to his project to that uses a cheap, discontinued cellphone gadget to create a Raspberry Pi controlled FM radio transmitter.

    The Sony-Ericsson MMR-70 radio transmitter apparently used to connect to a cell phone and broadcast music. But the Walkman cellphones in question are a little bit old in the tooth, so one can buy the transmitter units for cheap on the resale market. What makes the transmitters even more interesting is that you can activate and deactivate the radio, change frequency or output power, and even send RDS station … Read more

  • Protocol Snooping Digital Audio

    Protocol Snooping Digital Audio

    By Elliot Williams | November 12, 2014

    More and more clubs are going digital. When you go out to hear a band, they’re plugging into an ADC (analog-to-digital converter) box on stage, and the digitized audio data is transmitted to the mixing console over Ethernet. This saves the venue having to run many audio cables over long distances, but it’s a lot harder to hack on. So [Michael] trained popular network analysis tools on his ProCo Momentum gear to see just what the data looks like.

    [Michael]‘s writeup of the process is a little sparse, but he name-drops all the components you’d need to get the job … Read more

    Nothing’s as Vain as a Phone Taking a Selfie of Itself… with Itself

    By Sarah Petkus | November 12, 2014

    The selfie: pop culture’s most frivolous form of self-expression is also probably one of the most human acts you could find yourself doing in a day. Everyone is guilty of snapping a quick pic from time to time with the expectation that it will leave an impression on those who see it. All of the implications surrounding why we do this support our deep-seated need to sculpt an identity for ourselves using others as the hammer and chisel. So, consider how upside-down the world would feel if you caught a robot posing for a shot in the mirror? What about … Read more
